Abstract: GA3 and NAA affect various aspects of plant physiology, mainly vegetative and flowering attributes including yield. A field experiment was carried out during 2015-16, at the Horticulture Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut to find out the response of foliar application of GA3 and NAA on vegetative and flowering attributes of tomato cv. Pusa Rohini. The two bio-regulators i.e. GA3 and NAA ware used in different concentration i.e. GA3 (20, 30, 40 and 50 ppm) and NAA (15, 20, 25 and 30 ppm) and Control (distilled water spray). All variables parameters related to vegetative growth and flowering parameters were significantly influenced by different concentrations of the plant bio-regulators. Results revealed that between both the growth regulators, the foliar application of GA3 (50 ppm) registered significantly higher vegetative growth viz., plant height (101.45cm) & internodes length (6.20 cm) and flowering parameters viz., minimum number of days to first flowering (24.60) & maximum number of flower per plant (50.13) as compared to other treatments.
